Special Issue Information

Dear Colleagues,

In the dynamic landscape of dairy production, traditional methodologies are yielding ground to innovative approaches that prioritize sustainability and ethical considerations, encompassing not only production but also reproduction aspects within the dairy industry. With escalating concerns surrounding environmental impact and animal welfare, the exploration of alternative sources for dairy production has become imperative. This Special Issue of Dairy is dedicated to delving into the theme of "How Dietary Feeding Nutrients Effect Reproduction, Health, and Milk Production". We aim to comprehensively investigate the viability of these novel options within the context of dairy cattle nutrition and reproduction. Our aim is to assess their efficacy in meeting the multifaceted demands for productivity, reproductive efficiency, and profitability while simultaneously addressing sustainability challenges and elevating animal welfare standards. We welcome scholarly contributions that elucidate recent advances and insights in this dynamic intersection, foster knowledge dissemination, and facilitate the progression towards a more sustainable future in dairy production. Authors are invited to submit manuscripts exploring various facets of alternative dairy sources, from nutritional compositions to reproductive implications, contributing to the collective understanding of this evolving landscape.

This study aimed to compare calcium oxide (CaO) and calcium chloride (CaCl2) as calcium sources for coconut fatty acid distillate (CFAD) calcium soap (Ca-soap) production and to evaluate the supplementation ratios of unprotected and protected CFAD in dairy rations to optimize rumen function. This research included two steps: (1) assessing the protection strength of Ca-soap made with CaO and CaCl2 at mole ratios of Ca to CFAD of 1, 1.5, 2, and 2.5; (2) evaluating CFAD supplementation in an in vitro dairy ration study using a 5 × 4 randomized factorial block design. Factor A compared unprotected and protected CFAD ratios of A1 = 100:0, A2 = 75:25, A3 = 50:50, A4 = 25:75, and A5 = 0:100, and factor B compared supplementation levels of B1 = 0%, B2 = 1%, B3 = 2%, and B4 = 3%. CaCl2 at a 2.5-mole ratio to CFAD produced the lowest acid value and the carboxylic acid (C=O) chemical bond. Complete protection (0:100) exhibited the highest densities of Bacteroides and nutrient digestibility (p < 0.05) without significantly affecting rumen fermentability (p > 0.05). Higher CFAD levels significantly reduced methanogens and protozoa (p < 0.05) without significantly affecting estimated methane production. In conclusion, CaCl2 at a 2.5-mole ratio to CFAD provided the best protection, and its complete protection in CFAD supplementation optimized rumen function. Full article

Artisan goat cheeses (AGCs) from four different producers in Coahuila, Mexico, along with a pasteurized goat cheese (C), were subjected to a comprehensive analysis covering production, chemical, microbiological aspects, and texture. The study aimed to discern the impact of feeding practices, seasonality, and manufacturing technology on their properties. Aspects such as the manufacturing production, chemical composition, microbiological load, and texture characteristics were analyzed. The results highlighted a higher protein content in the cheeses from grazing goats (14.51%), while the highest fat (14.25%) and ash (3.27%) contents were found in the cheeses made during spring from stabled goats. Correlations were noted between the protein content and hardness, as well as the acidity and adhesiveness. Most of the analyzed cheeses showed microbiological levels higher than those allowed by national regulations, with counts ranging from 1 to 7.5 Log cfu g−1 for total coliforms, 2.39 to 7.52 Log cfu g−1 for molds and yeasts, as well as 2.16 to 6.53 Log cfu g−1 for Staphylococcus. The findings of this study offer a comprehensive insight of the effects of feeding practices, seasonality, and manufacturing technology on AGC properties, potentially guiding improvements in both production processes and product quality.
